"Handcrafted Steel-Copper Dual-Layer Tumbler Glass with Hammered Copper Exterior and Polished Stainless Steel Interior" About

• • Stainless Steel Interior Layer: The inner chamber is lined with a high-grade, food-safe stainless steel core. Unlike raw unlined copper, this surface is completely rust-proof, scratch-resistant, and non-reactive with acidic juices, carbonated sodas, or hot beverages. This ensures zero metallic taste transfer and a highly hygienic drinking surface.
  • Copper Exterior Shell: The outer layer is forged from premium pure copper. Copper features exceptional thermal conductivity, instantly pulling the chill from ice cubes or cold water to create a cool exterior feel [indianartvilla.in].
• Form Factor & Ergonomics:
  • Tapered Profile: Designed with clean, slightly tapered vertical walls that flare gently outward toward a wide rim, providing a balanced physical grip and easy stacking storage.
  • Rolled Safety Rim: The top edge features a precision-rolled safety lip where the internal silver steel cleanly overlaps the outer copper layer, providing a smooth mouthfeel [amazon.in].
  • Flat Balanced Base: Built with a structurally stable, flat bottom to minimize the risk of accidental tipping on crowded tables or serving trays [lacoppera.com].

• Dimpled Hand-Hammered Finish: The entire outer copper layer features a manually dimpled texture. This handcrafted pattern scatters ambient room light beautifully, producing a warm, multi-faceted metallic glow.
• Smudge and Fingerprint Resistance: Beyond its visual charm, the textured hammer facets are highly functional in high-traffic commercial restaurant environments, naturally minimizing the appearance of daily fingerprint oils, smudges, and minor water streaks.
• Dual-Tone Palette Contrast: The striking visual interplay between the polished silver steel rim and the rich rose-gold copper body creates a sophisticated contrast that coordinates seamlessly with modern dinnerware styles and antique brass tableware settings.

1. The Solution: Prepare a gentle cleaning paste using specialized metal polish, Pitambari powder, or a traditional homemade mixture of concentrated lemon juice and standard iodized salt [rosebuck.in].
2. Application: Gently rub the paste over the outer copper sections using a soft cellulose sponge or microfiber cloth [rosebuck.in].
3. Strict Avoidance: Never use steel wool, wire brushes, or harsh abrasive pads, as they will permanently scratch the smooth polished surfaces and wear away the fine texturing.
4. Rinse: Flush thoroughly under cold tap water to completely clear the acidic paste.

• Strict Hand Wash Only: Never place this tumbler inside a dishwasher [hotel needs india]. The intense water temperatures, prolonged steam cycles, and harsh chemical detergents will loosen the dual-metal bond, cause copper tarnish, and strip the outer polish.
• Immediate Microfiber Towel Drying: Wipe the glass completely dry with a soft cloth immediately after rinsing [rosebuck.in]. Allowing it to air-dry will cause permanent hard-water mineral crusting, water spots, and accelerated oxidation marks across the polished finish [rosebuck.in].
